[0002] Casting is a common production process for rare metal molding. With the increasing application of rare metals, the requirements for the shape of rare metals are getting higher and higher, and casting molding is an indispensable process link. However, most of the current casting processes place the raw materials in a furnace to melt, and then manually cast them into a mold, but this casting method has many defects: First, the transfer of molten metal is time-consuming and labor-intensive, requiring a lot of manual operation, and the molten metal is very likely to spill and splash during the operation, which may scald workers; secondly, the molten metal mold adopts a split type, which requires manual clamping, which is time-consuming and labor-intensive, and the clamping fasteners are easily damaged due to long-term disassembly and assembly, resulting in unnecessary waste; thirdly, due to the different physical properties of rare metals, the temperature of the casting process directly affects the appearance quality and cost of the product.

[0067] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned figures are used to distinguish different objects, not to describe a specific order or a primary and secondary relationship. "Multiple" appearing in this application refers to more than two (including two).

[0069] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0070] The automatic casting equipment according to the present application is described in detail below with reference to the accompanying drawings.

[0071] Reference Figures 1 to 9 The automatic casting equipment of the present application includes a heating and conveying device 1, a hydraulic propulsion device 2, a casting device 3, a clamping device 4 and a mold opening device 5.

[0072] In the present application, the structure and installation of the automatic casting equipment are simple, the operation is convenient, and the production is safe and effective. Based on the coordinated cooperation between the heating and conveying device 1, the hydraulic propulsion device 2, the casting device 3, the clamping device 4 and the mold opening device 5, automated continuous production is realized, which not only improves the product quality and production efficiency, but also greatly reduces the production cost and labor intensity, while improving the safety of production and better meeting the production requirements.

[0073] Reference Figure 1 and Figure 2 The heating and conveying device 1 and the casting device 3 are arranged opposite to each other in the transverse direction X, and one end of the heating and conveying device 1 (i.e., the end close to the casting device 3) is located between the hydraulic propulsion device 2 and the clamping device 4. The heating and conveying device 1 is used to heat the mold S and convey the mold S to the one end of the heating and conveying device 1 (i.e., in front of the mold hydraulic propulsion device 2) along the transverse direction X.

[0074] In some embodiments, reference Figure 2The heating and conveying device 1 may include a first heating component 11, a heat conducting block 12 and a conveying mechanism 13. The first heating component 11 is disposed on the heat conducting block 12 and is used to heat the heat conducting block 12. The heat conducting block 12 forms a heating tunnel 121, and the heating tunnel 121 is used for the mold S to pass through. The conveying mechanism 13 is located below the heat conducting block 12 and is used to drive the mold S to move in the heating tunnel 121.

[0075] In the heating and conveying device 1, since the first heating component 11 indirectly heats the mold S through the heating tunnel 121 of the heat conducting block 12, when the mold S moves in the heating tunnel 121 via the conveying mechanism 13, the mold S is evenly heated in the heating tunnel 121. This indirect heating method is not only convenient for controlling the temperature in the heating tunnel 121, but also can ensure that the temperature of each area in the heating tunnel 121 is uniform, thereby achieving uniform heating of the mold S, thereby reducing the temperature difference between the mold S and the cast metal liquid, thereby ensuring the smoothness of the product surface and saving the manual polishing process.

[0076] In some embodiments, reference Figure 2 The first heating assembly 11 may include a first heating sleeve 111 and a first junction box 112. The first heating sleeve 111 is disposed on the heat conductive block 12, and the first junction box 112 is electrically connected to the first heating sleeve 111 and an external power supply device (not shown).

[0077] In some embodiments, the first heating jacket 111 is made of a heat-conducting material, and the first heating jacket 111 can be disposed on the outside or inside of the heat-conducting block 12 .

[0078] In some embodiments, the number of first heating jackets 111 may be one, wherein the one first heating jacket 111 may correspond to only one first junction box 112. Of course, in order to improve heating efficiency, the one first heating jacket 111 may also correspond to multiple first junction boxes 112 at the same time.

[0079] In some embodiments, there may be a plurality of first heating jackets 111 , and the plurality of first heating jackets 111 are continuously arranged along the transverse direction X. Each first heating jacket 111 may be individually heated by a corresponding first junction box 112 , thereby ensuring heating efficiency.

[0080] In some embodiments, reference Figure 2 The heat conducting block 12 has a top wall 122 and two side walls 123, and the two side walls 123 and the top wall 122 together form a U-shaped heating tunnel 121. The first heating sleeve 111 is at least arranged on the top wall 122 of the heat conducting block 12. In order to ensure heating efficiency and heating uniformity, the first heating sleeve 111 can be arranged on the top wall 122 and the two side walls 123 of the heat conducting block 12 at the same time.

[0081] In some embodiments, reference Figure 2 The conveying mechanism 13 includes a conveyor belt 131, a plurality of mounting seats 132 and a driving motor (not shown). The plurality of mounting seats 132 are arranged at intervals along the transverse direction X, and each mounting seat 132 can be fixed on the conveyor belt 131 by bolts, and each mounting seat 132 is installed with a corresponding mold S. The conveyor belt 131 drives the mold S to move in the heating tunnel 121 under the action of the driving motor to heat it, and transports the heated mold S to a designated position (i.e., in front of the mold hydraulic propulsion device 2).

[0082] In some embodiments, reference Figure 2 and Figure 3 Each mounting seat 132 may include a fixing portion 132A and a mounting portion 132B. The fixing portion 132A may be fixedly connected to the conveyor belt 131 by bolts. The mounting portion 132B protrudes from the fixing portion 132A in the up-down direction Z and mounts the mold S.

[0083] In some embodiments, the mounting portion 132B is formed as a U-shaped structure with an opening, wherein the mold S is pushed into the clamping device 4 along the longitudinal direction Y through one side of the opening of the mounting portion 132B under the action of the hydraulic propulsion device 2 .

[0084] In some embodiments, the mounting portion 132B may be composed of three clamping walls 132B1 (eg, Figure 2 and Figure 3 The three clamping walls 132B1 are installed and clamp the corresponding mold S during the conveying process to ensure the stability of the mold S during the conveying process. Specifically, the three clamping walls 132B1 can be connected as a whole, or can be arranged at intervals along the circumference of the fixing portion 132A.

[0085] In some embodiments, reference Figure 2 The heating and conveying device 1 further comprises a support frame 14 and two mounting beams 15. The support frame 14 supports the two mounting beams 15, the two mounting beams 15 are arranged opposite to each other in the longitudinal direction Y, and the two mounting beams 15 together support the heat conducting block 12 and install the conveying mechanism 13.

[0086] Reference Figure 1 and Figure 4, the hydraulic propulsion device 2 and the clamping device 4 are arranged opposite to each other in the longitudinal direction Y, and the hydraulic propulsion device 2 is located behind the one end of the heating conveying device 1 in the longitudinal direction Y. When the mold S is transported to the one end of the heating conveying device 1 under the action of the heating conveying device 1, the hydraulic propulsion device 2 pushes the mold S on the one end of the heating conveying device 1 into the clamping device 4 along the longitudinal direction Y. Here, under the action of the hydraulic propulsion device 2, the heated mold S can be directly and quickly pushed into the clamping device 4, thereby not only avoiding the risk of scalding caused by manual handling of the mold S, but also greatly improving the mold handling efficiency.

[0087] In some embodiments, reference Figure 4 The hydraulic propulsion device 2 includes a hydraulic control station 21, a first cylinder 22 and a first piston rod 23. Specifically, a driving motor (not shown) is provided in the hydraulic control station 21, one end of the first piston rod 23 extends out of the first cylinder 22, and the other end is in the first cylinder 22 and connected to the driving motor, and the first piston rod 23 moves telescopically along the first cylinder 22 under the action of the driving motor, so that the one end of the first piston rod 23 pushes the mold S on the heating conveying device 1.

[0088] In some embodiments, reference Figure 4 The hydraulic propulsion device 2 further includes a push plate 24. The push plate 24 is fixed to the one end of the first piston rod 23 and pushes the mold S on the heating and conveying device 1 under the action of the first piston rod 23. The setting of the push plate 24 increases the contact area between the hydraulic propulsion device 2 and the mold S, thereby increasing the stability of the mold S during the pushing process of the hydraulic propulsion device 2.

[0089] In some embodiments, reference Figure 3 The hydraulic propulsion device 2 further includes a frame structure 25 . The frame structure 25 is surrounded by a middle cavity, the hydraulic control station 21 is installed on the frame structure 25 in the middle cavity, and the first cylinder body 22 is fixed above the frame structure 25 .

[0090] Reference Figure 1 and Figure 5 The casting device 3 and the heating and conveying device 1 are arranged opposite to each other in the horizontal direction X, and the casting device 3 is located above one end of the clamping device 4 close to the hydraulic propulsion device 2. When the mold S is clamped by the clamping device 4, the casting device 3 casts the molten metal into the clamped mold S; and when the mold S clamped by the clamping device 4 completes the casting, it is moved to the mold opening device 5 under the action of the hydraulic propulsion device 2.

[0091] In some embodiments, reference Figure 5The casting device 3 includes a furnace 31, a sliding guide mechanism 32 and a driving mechanism 33. The furnace 31 is provided with a discharge port 31A and a feed port 31B, and the furnace 31 is located above the sliding guide mechanism 32 and connected to the sliding guide mechanism 32. The driving mechanism 33 is connected to the furnace 31 and drives the furnace 31 to move along the sliding guide mechanism 32.

[0092] Here, based on the automation of the casting device 3, the molten metal in the furnace 31 can be automatically injected into the mold S through the discharge port 31A, thereby not only avoiding the danger of spilling and splashing the molten metal when manually injecting the molten metal into the mold S, but also greatly improving the mold casting efficiency. In addition, because the furnace 31 can move along the sliding guide mechanism 32 (that is, the furnace 31 can move back and forth along the longitudinal direction Y) under the action of the driving mechanism 33, it is ensured that the discharge port 31A of the furnace 31 can accurately correspond to the mold S in the clamping device 4 to achieve accurate casting and the discharge port 31A continuously casts different molds S in the longitudinal direction Y, thereby greatly improving the mold casting accuracy and mold casting efficiency.

[0093] In some embodiments, reference Figure 5 The melting furnace 31 includes a furnace body 311 and a second heating component 312 . The furnace body 311 is connected to the discharge port 31A and the feed port 31B. The second heating component 312 is sleeved on the furnace body 311 and heats the furnace body 311 .

[0094] In some embodiments, reference Figure 5 The second heating assembly 312 includes a second heating sleeve 312A and a second junction box 312B. The second heating sleeve 312A is sleeved on the furnace body 311, and the second junction box 312B connects the second heating sleeve 312A and an external power supply device (not shown).

[0095] In some embodiments, reference Figure 5 The melting furnace 31 further includes a third heating component 313 , which is disposed at the discharge port 31A and heats the discharge port 31A to control the temperature of the molten metal in the discharge port 31A.

[0096] Since the furnace body 311 of the melting furnace 31 is heated separately by the second heating component 312, and the discharge port 31A is heated separately by the third heating component 313, it is convenient to control the temperatures of the furnace body 311 and the discharge port 31A separately, thereby reducing the temperature difference between the molten metal discharged through the discharge port 31A and the mold S, thereby ensuring the smoothness of the product surface and saving the manual polishing process.

[0097] In some embodiments, reference Figure 5The third heating assembly 313 includes a third heating sleeve 313A and a third junction box 313B. The third heating sleeve 313A is sleeved on the discharge port 31A, and the third junction box 312B connects the third heating sleeve 312A and an external power supply device (not shown).

[0098] In some embodiments, reference Figure 5 The sliding guide mechanism 32 includes a guide rail 321 and a slider 322. The guide rail 321 extends along the longitudinal direction Y, and the slider 322 is slidably disposed on the guide rail 321, and is located below the melting furnace 31 and connected to the melting furnace 31.

[0099] In some embodiments, reference Figure 5 The guide rails 321 and the sliders 322 are arranged in pairs, and the two guide rails 321 in the pair are arranged at intervals along the horizontal direction X, and each guide rail 321 is slidably connected to a corresponding slider 322.

[0100] In some embodiments, reference Figure 5 The driving mechanism 33 includes a second cylinder 331, a second piston rod 332 and a driving motor (not shown). One end of the second piston rod 332 extends out of the second cylinder 331, and the other end is located in the second cylinder 331 and connected to the furnace 31. The second piston rod 332 moves telescopically along the second cylinder 331 under the action of the driving motor, so that the furnace 31 slides on the sliding guide mechanism 32.

[0101] In some embodiments, reference Figure 5 The melting furnace 31 further includes a discharge valve 314. The discharge valve 314 is disposed at the discharge port 31A and is used to adjust the discharge amount of the discharge port 31A.

[0102] In some embodiments, reference Figure 5 The furnace 31 further includes an upper cover 315. When the metal raw material enters the furnace body 311 of the furnace 31 through the feed port 31B, the upper cover 315 cooperates with the feed port 31B to seal the feed port 31B. The metal raw material is melted in the furnace body 311, and then the molten metal liquid is injected into the mold S through the discharge port 31A.

[0103] In some embodiments, reference Figure 5 The casting device 3 further includes a bracket 34. The bracket 34 supports and installs the sliding guide mechanism 32 and the driving mechanism 33. Specifically, the bracket 34 can be formed as a frame structure.

[0104] Reference Figure 1 as well as Figures 6 to 8 The clamping device 4 and the hydraulic propulsion device 2 are arranged opposite to each other in the longitudinal direction Y, and one end of the clamping device 4 is located below the casting device 3, and the other end is located on one side of the mold opening device 5 in the longitudinal direction Y (that is, the other end of the clamping device 4 is located behind the mold opening device 5).

[0105] In some embodiments, reference Figure 6 The clamping device 4 includes a mounting frame 41, a first clamping roller assembly 42, and a second clamping roller assembly 43. The first clamping roller assembly 42 is fixedly arranged on the mounting frame 41, and the second clamping roller assembly 43 is slidably arranged on the mounting frame 41, and the second clamping roller assembly 43 and the first clamping roller assembly 42 are arranged opposite to each other in the transverse direction X and cooperate together to clamp the mold S. Under the pushing action of the hydraulic propulsion device 2, the mold S enters between the first clamping roller assembly 42 and the second clamping roller assembly 43 and squeezes the first clamping roller assembly 42 and the second clamping roller assembly 43 to both sides. At the same time, the mold S is automatically clamped by the first clamping roller assembly 42 and the second clamping roller assembly 43, so that there is no need to manually clamp the mold S, thereby improving production efficiency and reducing labor intensity.

[0106] In some embodiments, reference Figure 6 , when the first nip roller assembly 42 and the second nip roller assembly 43 are respectively provided in plurality, one first nip roller assembly 42 corresponds to one second nip roller assembly 43 .

[0107] It should be noted that the mold S to be cast and the already cast mold S are both located in the clamping device 4 and are clamped by the corresponding first clamping roller assembly 42 and second clamping roller assembly 43, respectively. Among them, the mold S to be cast is located in the part of the clamping device 4 close to the hydraulic propulsion device 2, and the already cast mold S is located in the part of the clamping device 4 far away from the hydraulic propulsion device 2. Under the pushing action of the hydraulic propulsion device 2, the mold S of the heating and conveying device 1 is pushed to the first clamping roller assembly 42 and the second clamping roller assembly 43 of the clamping device 4 closest to the hydraulic propulsion device 2. At the same time, the already cast mold S clamped by the first clamping roller assembly 42 and the second clamping roller assembly 43 farthest from the hydraulic propulsion device 2 is moved to the mold opening device 5 (that is, the clamping device 4 releases the already cast mold S). Therefore, the clamping device 4 of the present application cooperates with the hydraulic propulsion device 2 to realize automatic loosening of the mold S, thereby realizing automatic control, thereby improving production efficiency and reducing manual labor intensity.

[0108] In some embodiments, reference Figure 6 The mounting frame 41 includes a first mounting plate 411 and a second mounting plate 412. The first mounting plate 411 and the second mounting plate 412 are arranged opposite to each other in the transverse direction X, and the first mounting plate 411 is mounted with the first clamping roller assembly 42, and the second mounting plate 412 is mounted with the second clamping roller assembly 43.

[0109] In some embodiments, reference Figure 6 The mounting frame 41 further includes a base 413. The base 413 is located below the first mounting plate 411 and the second mounting plate 412, and is used to support and mount the first mounting plate 411 and the second mounting plate 412.

[0110] In some embodiments, reference Figure 6 and Figure 7 The first clamping roller assembly 42 includes a first clamping roller 421 and a first connecting column 422. The first connecting column 422 is inserted into the first clamping roller 421, and both ends of the first connecting column 422 are fixed to the mounting frame 41.
